  1. Scan your vehicle to verify P0420 is the only code present. ...
  2. Examine the exhaust system for damage and leaks. ...
  3. With the car running and at normal operating temperature, use the digital multimeter to check the voltage reading of the downstream O2 sensor.

SOURCE: TRAC OFF, VSC, and check engine lights are on in my 2004 Lexus ES

Often caused by a loose gas cap or fouled or failed air fuel O2 sensor. Check your gas cap is fully ratcheted, Drive a day or two. If lights don't clear you will need a code reader attached to the car to diagnose.

SOURCE: Repalcing the main beam headlight bulb on the 2004 Lexus ES 330

The bulb is held in place by a wire capture that hooks under a small metal hook on bottom of housing. The rubber shroud or boot needs to be pulled off first to expose the bulb and intermittent socket that actually holds the bulb. To remove the bulb push the wire capture (the end that is looped) toward the front of the car and then to the side to disengage the wire from the small hook, be sure to note the position of the plastic socket that the bulb plugs into as it only fits one way.Notice the tab on the bulb base faces up. The bulb does not fit snugly in the headlight socket, it is held in place entirely by the wire catch.

Lexus ES 330 2004 At what mileage does the radiator need to be serviced? Also, does it have an internal timing chain that needs to be serviced?


the coolant needs to be serviced @ 60k according to lexus reccomendation. theres a timing belt that needs to be changed @ 90k miles. I usually just change the coolant with the timing belt because you have to take the water pump off anyway and replace the engine coolant.

I have 2004 Lexus 330 and at 50,000 miles the service light came on. What the probable fix? Thanks.


I'm a Lexus tech,
You need to retreive a code from computer. Did you pump gas with car running. Will trigger Emission code P0440. Make sure gas cap is tight.
